W/P pulley is factory size. Crank Pulley is underdriven by 1/2". :TU: Ya got yer wish! I might add that the mounting surface of the aluminum is slightly thicker by about 1/4 of an inch, so for the W/P pulley this causes the clutch/fan mount to sitck out 1/4 inch further- and closer to the radiator. For most applications this should not be an issue. I am trying to source longer mounting studs that I will include with the W/P pulleys, and allen head capscrews for the crank pulleys. Erik
Andy- A typical OEM crank pulley would be 6.5 but these are 6" diameter, which coincidently is the same size as a "non-A/C" pulley (it just has a third groove). Therfore it can be used for either purpose. Erik
I've got some good news. After my final machining cost are in, I am getting a better break for the volume than I had originally estimated. This of course has brought my costs way down. So the recalculated price is $220.01 for the crank and $182.50 for the water pump ($402.51) for the pair. As for shipping, two pulleys (1 set) fit in in a medium flat rate Priority Mail USPS box for $10.95. This is the last call for the "introductory" price of $375 to those that have spoken for them first. I will now be releasing them over to be marketed and sold by Russ Martin. Erik
So here they are and open for purchase or contact Russ directly. http://cgi.ebay.com/ebaymotors/Buick-nailhead-NEW-3-groove-BILLET-ALUMINUM-PULLEYS-_W0QQcmdZViewItemQQhashZitem53e6a3d1c0QQitemZ360351781312QQptZVintageQ5fCarQ5fTruckQ5fPartsQ5fAccessories Erik

I notice in the ad it says 62-66. will these work on a 401 in a 61 electra without AC? boy these would look sharp!
They will bolt on all nailheads but I believe your groove offset spacing and set-up will be different, however you might be able to make them work. These are 3 groove. Take a look at the other examples in the photos I have posted earlier. I am not 100% sure for your application. Erik
It is true, they will wear just like any other aluminum pulley. I'll bet most nailheads aren't driven more that 500 miles a year anyway. ...and yes... they can be hard annodized. I have left them raw for the explicit purpose that anyone can polish them, clear coat, paint or powder coat, or as you pointed out- annodizing in any color or hard anodize of their choice. Good question! Erik
